* Under LSNG this exposes nsILocalStorageManager::Preload to ContentParent to
* trigger preloading. Otherwise, this is basically just a place for test logic
* that doesn't make sense to put directly on the Storage WebIDL interface.
*
* Previously, the nsIDOMStorageManager XPCOM interface was also used by
* nsGlobalWindowInner to interact with LocalStorage, but in these de-XPCOM
* days, we've moved to just directly reference the relevant concrete classes
* (ex: LSObject) directly.
*
* Note that testing methods are now also directly exposed on the Storage WebIDL
* interface for simplicity/sanity.
